Hi Gerd, 2.9 seems to have an xhci migration breakage, I've bisected it down to: commit ddb603ab6c981c1d67cb42266fc700c33e5b2d8f Author: Gerd Hoffmann <kra...@redhat.com> Date: Mon Jan 30 16:36:46 2017 +0100
xhci: don't kick in xhci_submit and xhci_fire_ctl_transfer I guess maybe there's a kick needed pre/post migrate? (it's https://bugzilla.redhat.com/show_bug.cgi?id=1436616 ) The symptoms on the destination are that the qemu prints: qemu-kvm: usb-msd: Bad signature 53425300 and the guest sees: xhci_hcd 0000:00:06.0: WARN Event TRB for slot 1 ep 0 with no TDs queued? xhci_hcd 0000:00:06.0: WARN Event TRB for slot 1 ep 2 with no TDs queued? xhci_hcd 0000:00:06.0: WARN Event TRB for slot 1 ep 3 with no TDs queued? and never gets any more IO on the USB disk. Any ideas? Dave -- Dr. David Alan Gilbert / dgilb...@redhat.com / Manchester, UK
